Demonstrated ability to lead the technical design and implementation of complex networking and security initiatives, balancing scalability, resiliency, and risk management.
Advanced proficiency administering and troubleshooting both Windows and Linux environments, with the ability to diagnose and resolve issues across networking, systems, and applications.
Extensive experience with scripting and automation using PowerShell, Bash, and/or Python to improve reliability, reduce manual effort, and enforce standards.
Hands-on experience building and operating monitoring, observability, and alerting solutions using tools such as Zabbix, Azure Monitor, Prometheus, Grafana, Datadog, and centralized logging platforms (e.g., ELK, Loki, Graylog).
Strong working knowledge of Microsoft Entra ID / Active Directory, identity federation, and access control models in hybrid and cloud-integrated environments.
Proven ability to take full ownership of technical outcomes, including architecture decisions, implementation, documentation, and ongoing operational excellence.
Excellent communication and stakeholder management skills, with the ability to translate complex technical concepts, risks, and trade-offs into clear business-facing language.
Experience providing Tier‑3 operational support and participating in after-hours on-call rotations for critical infrastructure services.
Solid understanding of ITIL practices (Incident, Change, and Problem Management), with experience improving operational processes and system stability over time.

What you’ve done:

5+ years experience supporting engineering enterprise environments across networking, security, Windows and Linux systems, and cloud platforms.
Expert knowledge of core networking protocols and services, including TCP/IP, DNS, DHCP, routing, and VPN technologies (site-to-site and client-based).
Strong experience with Fortinet firewalls and networking equipment; Fortinet certifications (e.g., NSE) are a strong asset.
Proven experience designing and supporting cloud and hybrid networking solutions, with Microsoft Azure strongly preferred (AWS or GCP experience considered an asset).
Hands-on experience delivering Infrastructure as Code using tools such as Terraform, Ansible, and/or Chef to provision and manage network and system resources.
Working knowledge of database platforms such as Microsoft SQL Server and PostgreSQL, particularly as they relate to infrastructure, performance, and availability considerations.
Experience implementing enterprise observability, monitoring, and alerting strategies using. platforms such as Azure Monitor, Prometheus, Datadog, and related tooling.

Working Conditions:

What’s in it for you:

Generous time off: Start with 3 weeks of vacation, plus extra flex days to recharge.
Comprehensive benefits package: Includes medical, dental, vision, health spending account, and Teladoc virtual care.
